Computer Features  
The following features are standard to the computers basic architecture.  
AGP Video  
An accelerated graphics port (AGP) video connector on the system board  
and an AGP expansion card are standard features. AGP is a bus architecture  
that increases video performance by routing video signals through a  
dedicated graphics bus rather than sending video signals on the PCI bus.  
BIOS  
The basic input/output system (BIOS) is software that enables your  
computer to communicate with peripheral devices (such as the keyboard,  
mouse, and monitor) without using programs on the hard drive.  
The battery in your computer maintains the BIOS settings in  
complementary metal-oxide semiconductor (CMOS) memory even when  
the computer is turned off.  
You can change the BIOS settings through the Setup program. Open Setup  
by pressing F1 when you are prompted as your computer starts.  
Cache Memory  
Your computer includes level 1 (L1) and level 2 (L2) cache. This cache  
memory is located on the processor. Cache reduces the average time  
required for the processor to get the data it needs from the main memory by  
storing recently accessed data in the cache.  
Connectors  
The standard input/output (I/O) connectors included with the computer are:  
Keyboard port  
Mouse port  
Two serial ports  
10 E-5250 User’s Guide

Parallel port  
Two universal serial bus (USB) ports  
Audio-out jack  
AGP video port  
Network connector  
External SCSI connector.  
Drives  
The standard configuration for your computer includes a 1.44-MB 3.5-inch  
diskette drive, a hard drive, and a CD-ROM drive. You can install up to  
seven additional drives (depending on drive height) in the computer.  
Two IDE controllers and a diskette controller are integrated into the system  
board. A SCSI controller card is also included as a standard feature. For  
instructions on installing drives, see the “Installing Components” chapter in  
the Maintaining and Troubleshooting Your E-5250 System guide.  
The first 2 gigabytes (GB) of the hard drive shipped with your Windows  
NT computer are partitioned as file allocation table (FAT)16. The rest of the  
space on the drive is partitioned as NT file system (NTFS). Any other hard  
drives shipped from the factory with your computer are partitioned as  
NTFS.  
FAT16 and NTFS are different methods that the operating system uses to  
organize and keep track of files on a hard drive. Your hard drive is divided  
into both types of partitions to support your 16-bit software and your 32-bit  
software.  
FAT16 supports the older 16-bit software and is limited to partitions of 2  
GB or less. NTFS supports 32-bit software and large drive sizes. Unlike  
FAT16 partitions, NTFS partitions cannot be viewed with Microsoft® disk  
operating system (MS-DOS®) diagnostic utilities, such as fdisk. See your  
Windows NT manual for more information on NTFS.

Expansion Slots  
Expansion slots inside the computer enable you to install add-in cards, such  
as a SCSI (small computer system interface) controller. Your computer  
includes one AGP slot, six 32-bit peripheral component interconnect (PCI)  
slots, and one 8/16-bit industry standard architecture (ISA) slot.  
The maximum number of slots that you can fill is seven. The ISA slot and  
PCI slot next to each other share a slot location. You can use one or the  
other slot, but not both. For instructions on installing add-in cards, see the  
“Installing Components” chapter in the Maintaining and Troubleshooting Your  
E-5250 System guide.  
Intel 440GX Chip Set  
The Intel® 440GX chip set provides support for Pentium® II Xeon™  
processors. The chip sets Quad Port Acceleration improves bandwidth  
between the processor, the AGP, 100-Mhz SDRAM, and the PCI bus.  
Manageability  
The status of your systems hardware is monitored through the hardware  
management application specific integrated circuit (ASIC) on the system  
board. Monitored information includes voltage and chassis intrusion.  
You can access the monitoring information through Intel LANDesk Client  
Manager, which provides a quick system health indicator.  
Memory  
Your computer comes standard with error correcting code (ECC)  
synchronous dynamic random access memory (SDRAM). You can install  
up to 2 GB of memory in the four memory slots on the system board. You  
can fill the slots with DIMMs of the sizes 128 MB, 256 MB, and 512 MB  
(when available).  
Important!  
See the  
Maintaining and  
Troubleshooting Your E-  
guide for a  
5250 System  
complete description of the  
type of DIMMs you can  
install in your computer.  
No jumper settings are required for the memory size or type because this  
information is automatically detected by the BIOS. For information on  
installing additional memory, see the “Installing Components” chapter in  
the Maintaining and Troubleshooting Your E-5250 System guide.

Networking  
For easy connection to a network, a PCI-based 10/100 megabits per second  
(Mbps) networking card is provided as a standard component of your  
computer.  
Processor  
Your computer includes support for dual Intel Pentium II Xeon processors.  
The Pentium II Xeon processor is designed to support the needs of single-  
and multithreaded workstation applications. The processor includes fast  
ECC level 2 cache and multiprocessing capabilities.  
One processor comes standard in the computer. The other processor slot is  
filled with a terminator card. If you add a second processor, both processors  
should be of the same clock speed and have the same amount of cache  
memory.  
A voltage regulator connector on the system board provides support for a  
voltage regulator module that is installed if your system includes two  
processors.  
Installing two processors enables your computer to take advantage of  
multithreading on some 32-bit graphics applications. These applications  
may run faster with two processors than with one. See your software  
documentation for more information.  
For information on removing and installing a processor, see the “Installing  
Components” chapter in the Maintaining and Troubleshooting Your E-5250  
System guide.

Maintaining the Hard Drive  
Hard drives need regular maintenance because running the system software  
divides files, creates spaces between data, and otherwise decreases hard  
drive performance. Windows NT provides the Check Disk utility to  
maintain the hard drive. Check Disk enables you to check the drive for  
errors, fix file system errors, and attempt to recover bad sectors on the  
drive.  
Use Check Disk from once a week to once a month, depending on how  
often you use your computer. Also use Check Disk whenever you have any  
hard drive problems.  
To use Check Disk  
Right-click Start and then click Explore.  
1.  
2.  
In the Windows NT Explorer window, right-click the drive you want to  
check. You can only check one drive at a time.  
Click Properties.  
3.

Protecting Against Viruses  
A virus is a program written with malicious intent for the purpose of  
creating havoc in a computer system. It attaches itself to executable files or  
boot sectors, so it can replicate and spread. Some viruses may only cause  
your system to beep or display messages or images on the screen. Other  
viruses are highly destructive and corrupt or erase the contents of your files  
or diskettes. To be safe, never assume any virus is harmless.  
Viruses spread through direct contact with executable programs or boot  
sectors. Diskettes used in a contaminated system can get a virus and  
transfer the virus when used in another system. A virus can also spread  
through programs downloaded from bulletin boards or the Internet.  
To protect your system against viruses  
Obtain an antivirus program and scan your system regularly.  
Make backup copies of all files and write-protect the diskettes.  
Obtain all software from reputable sources and always scan new  
software for any viruses before installing files.  
If you suspect your system has been infected, find and remove the viruses  
immediately using an antivirus program. Next, turn off your system and  
leave it off for at least 15 seconds before turning it back on. This is the only  
way to ensure the virus does not remain in your system RAM.

3.  
Cup your hand under the mouse and turn your mouse right-side up.  
The roller ball should drop into your hand. If it does not, gently shake  
the mouse until the ball drops out of the socket.  
Use adhesive tape to pick up any dust or lint on the surface of the ball  
and wipe away dirt or lint inside the ball socket. You can also blow into  
the socket to remove dirt and lint. If foreign matter is trapped inside  
the socket, use a cotton swab dipped in isopropyl alcohol to loosen it.  
Let surfaces dry completely after cleaning.  
4.  
Return the ball to the socket and replace the cover.  
5.  
Cleaning the Keyboard  
Occasionally, you should clean the keyboard to free it of dust and lint  
particles trapped under the keys. The easiest way to do this is to blow  
trapped dirt from under the keys using an aerosol can of air with a narrow,  
straw-like extension.

Use a soft cloth and window cleaner to clean the monitor screen. Squirt a  
little cleaner on the cloth (never directly on the screen), and wipe the screen  
with the cloth.  
Cleaning the Computer and Monitor Cases  
Always turn off the computer and other peripherals before cleaning any  
components.  
Use a damp lint-free cloth to clean the computer case, monitor case,  
keyboard, speakers, and other parts of your system. Avoid abrasive or  
solvent cleaners because they can damage the finish on your components.

Terms and Definitions  
This list of terms should help you get acquainted with terms used in your  
computers documentation and in your system software.  
Applications - Software installed on your system. Sometimes called  
programs.  
BIOS - Basic input/output system. The BIOS is software that is  
independent of any operating system. It enables the computer to  
communicate with the monitor, keyboard, and other peripheral devices  
without using programs on the hard disk.  
The BIOS on your computer is flash BIOS, which means that is has been  
recorded on a memory chip that can be updated if needed.  
Boot - To load the first software program (usually the operating system)  
that starts your computer. To perform a cold (or hard) boot, you turn the  
computer on when it is off. To perform a warm (or soft) boot, you reset the  
computer when it is already turned on.  
Boot disk - A disk containing operating system programs required to start  
your computer. A boot disk can be a diskette, hard drive, or CD.  
Byte - The basic unit of measure for computer memory. A character, such  
as a letter of the alphabet, uses one byte of memory. Each byte is made up  
of eight bits. Computer memory is often measured in kilobytes (1,024  
bytes) or megabytes (1,048,576 bytes).  
Cache memory - Cache is very fast memory that can be located in the  
processor. Cache reduces the average time required for the processor to get  
the data it needs from the main memory by storing recently accessed data in  
the cache.  
CMOS memory - Complementary metal oxide semiconductor memory.  
CMOS memory is memory that is retained even when the computer is  
turned off. The Setup program settings and other parameters are maintained  
in CMOS memory.  
Default - The option that the software or system uses when you have not  
made a choice yourself.  
Disc - A compact disc (CD).

Disk - The device used by the computer to store and retrieve information.  
Disk can refer to a diskette or a hard disk.  
Diskette - A removable disk, also called a floppy.  
Hard drive - The drive installed inside your computer that stores all your  
system and data files. Depending on its configuration, the computer may  
have more than one hard drive. Each drive is assigned its own drive letter. If  
you have only one drive, its drive letter is C, and it is often called “the C  
drive.”  
I/O - Input/output. Refers to devices, such as printers, whose purpose is to  
enter data into a computer or extract data from a computer. An I/O device is  
accessed through an I/O address: a location in memory reserved for the  
device to exchange information between itself and the rest of the computer.  
IRQ - Interrupt request line. The IRQ is a hardware line that a device uses  
to signal the processor when the device needs the processors services. The  
number of IRQs is limited by industry standards.  
Operating system - A program that supervises the computers operation,  
including handling I/O, networking and connectivity, and device drivers.  
Path - A sequence of information that directs the system to the file it needs.  
For example, c:\windows\bubbles.bmp is the path to a graphics file on  
your system. The c: tells the system it is on the C hard drive, the \windows  
tells the system it is in the windows folder, and bubbles.bmp is the file.  
Pixel - A pixel is an individual dot in a graphic displayed on your computer.  
Pixels are so close together that they look as though they are connected.  
POST - Power-on self-test. POST tests your computers components  
whenever you turn on the computer.  
Programs - Software installed on your system. Programs are sometimes  
called applications.  
RAM - Random access memory. RAM is the computers system memory.  
You can write to and read from RAM. Information stored in RAM is  
temporary and is erased when the computer is turned off.

Refresh rate - The refresh rate is the rate at which the image on the monitor  
screen is rewritten to the screen. A fast refresh rate helps keep the image  
from flickering.  
Resolution - The resolution is the sharpness or clarity of the image on the  
monitor screen. Resolution is measured by the number of pixels the screen  
can display. For example, a resolution of 800x600 means that the screen can  
display 800 pixels in a row and can display 600 rows. The more pixels  
displayed, the higher the resolution and the clearer the images.  
ROM - Read-only memory. Permanent computer memory dedicated to a  
particular function. For example, the instructions for starting the computer  
when you first turn on power are contained in ROM. You cannot write to  
ROM.
